Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.
After three years in which global carbon emissions scarcely rose, 2017 has seen them climb by 2%, as the long-anticipated peak in global emissions remains elusive.
The Amazon is the largest rainforest in the world.
Last week Brazil opened thousands of kilometres of previously protected Amazon rainforest to mining, in a bid to combat ongoing political and economic disasters.

Why is it so hard to reach consensus about how to slow climate change? Multiple time lags get in the way: some make it hard to convey the risk, while others prolong the search for solutions.
Giant kelp can grow up to 60cm a day, given the right conditions.

In an extract from his new book, Tim Flannery explains how giant kelp farms could suck carbon dioxide from the air and store it in the ocean’s depths, while encouraging species like fish and oysters.
Extreme wet years are getting wetter and more common. This means Australia’s terrestrial ecosystems will play a larger role in the global carbon cycle.
Plants absorb carbon and store it in the land.

Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
Rice cultivation is one of the ways food production pumps methane into the atmosphere.

Forests take longer than expected to rebound from droughts, diminishing their role as global carbon sinks.
Mangroves are still be cleared for aquaculture expansion. Since 1989, 6600 hectares of Tanjung Panjang Nature Reserve’s original 13,300 ha of mangroves have been converted.

Mangroves, hectare for hectare, store more carbon than any other forests. But they are also among the most threatened. New projects in Indonesia show how mangroves might be restored.
Lush rainforest above ground… spare a thought for what’s happening in the soil.
Tim Mowrer
It’s no exaggeration to say the tropics drive our planet’s carbon cycle – the constant transfer of carbon back and forth, on a global scale, between living things and the environment. Understanding the…
The swollen Fitzroy River in Queensland, Australia, where heavy rains in early 2011 led to extraordinary regrowth with a global impact.

Record-breaking rains triggered so much new growth across Australia that the continent turned into a giant green carbon sink to rival tropical rainforests including the Amazon, our new research shows…
